Celo is a mobile-first blockchain platform that makes financial dApps and crypto payments accessible to anyone with a mobile phone. Celo enables native and non-native digital assets–both cryptographic and Central Bank Digital Currencies (CBDCs)–to circulate freely across devices, carriers, and countries. This makes money mobile, global and accessible like never before.
Celo’s Proof-of-Stake (PoS) consensus mechanism and automatic daily carbon offsets make Celo the world's first carbon-negative blockchain, offsetting over 2,285 tons of carbon to-date.

Official golang implementation of the Celo blockchain, based off of the official golang implementation of the Ethereum protocol. Prebuilt Docker images are available for immediate use: us.gcr.io/celo-testnet/celo-node. See docs.celo.org/getting-started for a guide to the Celo networks and how to get started.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.
decentralized-platform decentralized-application blockchain cryptocurrency etherWe intend for this project to be an educational resource: we are excited to share our wins, mistakes, and methodology of iOS development as we work in the open. Our primary focus is to continue improving the app for our users in line with our roadmap. The best way to submit feedback and report bugs is to open a GitHub issue. Please be sure to include your operating system, device, version number, and steps to reproduce reported bugs. Keep in mind that all participants will be expected to follow our code of conduct.

Whilst popular cryptocurrencies such as Bitcoin and Ethereum can be traded on external exchanges, and Ethereum allows users to create new tokens on the platform using a smart contract, Waves includes this functionality in its core software and wallet. Users can create, transfer and exchange blockchain tokens on a peer-to-peer basis, paying transaction fees in the native WAVES token.
cryptocurrency-exchange exchange wallet decentralized-exchange cryptocurrency digital-assetsWelcome! This is a Python-based Dash app meant to track whale activity in buy / sell walls on crypto-currency exchanges (presently just operational for GDAX, but more exchanges to come). This document aims to explain the purpose, functionality, and future of this project. Please do share this with your fellow coders / traders / crypto-aficionados, donate via the donation addresses included in the "Support Needed" section below, and contribute to the future of this project by calling out issues, requesting new features, and submitting pull requests to improve the app. If you want to use a hosted version of the app, check out this link here which has been graciously hosted by a member of the Ethereum community while we raise money via donations to migrate to AWS. If for any reason the page does not load properly, feel free to let us know via an issue, but more than likely it is because we are updating to the newest version of the codebase or performing maintenance.

Status is a free (libre) open source mobile client targeting Android & iOS built entirely on Ethereum technologies. That's right, no middle men and go-ethereum running directly on your device. We believe in a medium of pure free trade, economies with fair, permission-less access and a world without intermediaries. We want to create policies that can exist between friends or scale globally, we want to communicate securely and be uninhibited by legacy systems.

ethereum dapp solidity ethereum-contractCryptocurrencies and smart-contracts on top of a blockchain aren't the most trivial concepts to understand, things like wallets, addresses, block proof-of-work, transactions and their signatures, make more sense when they are in a broad context. Inspired by naivechain, this project is an attempt to provide as concise and simple an implementation of a cryptocurrency as possible. From Wikipedia : A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange using cryptography to secure the transactions and to control the creation of additional units of the currency.

This repository contains the draft of the book, currently in progress, scheduled for publication in Q4'2018 by O'Reilly Media. The publication date has been delayed, unfortunately, due to some personal issues. Expect to see content developed and pushed here in Q1 and Q2 2018.

awesome bitcoin ethereum smart-contracts blockchain cryptocurrency awesome-listEthereum is gaining a significant popularity in the blockchain community, mainly due to fact that it is design in a way that enables developers to write decentralized applications (Dapps) and smart-contract using blockchain technology. Ethereum blockchain is a consensus-based globally executed virtual machine, also referred as Ethereum Virtual Machine (EVM) by implemented its own micro-kernel supporting a handful number of instructions, its own stack, memory and storage. This enables the radical new concept of distributed applications.
